The present invention relates to plumbing .ap-

-paratus and has for one of its objects the prowherein concrete or otherflooring materials are applied around the associated soil pipe, it isdesirable that the xture holding member may be easily placed in accurateposition with respect to its associated soil pipe sothat the fixture maybe 'anchored to its holding member without diniculties. The fixtureholding member is usually embedded in concrete, but in the process ofpouring the concrete or when the concrete is in the process ofhardening, the fixture holding member is often times unintentionallymoved from its correct position, and consequently, diiculties are laterencountered when an attempt is made to mount the plumbing fixture on itsholding member.

It is, therefore, an object of the present invention to provide improvedapparatus for assuring accurate position of a xture holding member afterconcrete or other flooring material is poured around the associated soilpipe.

Another object of the present invention is to provide an improved toolwhich serves to define a predetermined annular opening around the kendof a soil pipe when concrete or other liooring material is appliedaround the soil pipe.

A further object of the present invention is to vprovide an arrangementwhereby the aforesaid tool is firmly maintained in position during thetime that such concrete or flooring material is applied around the soilpipe.

The features of the present invention which are believed to be novel areset forth with particularity in the appended claims. This inventionitself, both as to its organization and manner of operation, togetherwith further objects and advantages thereof, may be best understood byreference to the following description taken in connection with theaccompanying drawings in which:

Figure 1 is a view in elevation and partly in section of an assembly ofapparatus incorporating the present invention.

Figure 2 is a sectional view of the soil pipe and associated concreteshown in Figure 1 after the assembly of apparatus shown therein isremoved, and further incorporates a correspond- 4 Claims.

Figure 3 is a sectional view similar to Figure 2 but with the fixtureholding member in place.

Figure4 is a perspective view of a tool shown in Figure 1 embodying thepresent invention.

In accordance with the present invention, an annular conical shapedspace I0 is provided withinwhich the plumbing xture holder II may beplaced incorrect aligned position with respect to the end of the soilpipe I2.

The annular space I0 is formed during the time the concrete I3 is pouredand allowed to harden around the soil pipe I2, a shield member yI4 beingfirmly maintained in adjusted position during such pouring and hardeningperiods. The shield member I4 comprises a hollow truncated conicalmember I5 having a web member I6 which serves as a fastening meansintermediate the ends thereof with the plane of the web memvber I6perpendicular to the longitudinal axis of the member I5. 'I'he member I6has a centrally located aperture I1 through which a test plug assemblyI8 may pass to hold the composite shield member I4 in adjusted position.

`The test plug assembly I8 serves two purposes; namely, ('1) to supportshield member in adjusted position; and (2) to provide a uid tightconduit and connection with the soil pipe I2, so thatV the soil pipe I2and its connection with other soil pipe (not shown) may be suitablytested by applying thereto uid under pressure which enters'through thevalve 20 and passes downwardly through the central pipe 2l into the soilpipe I2.

Resilient annular ring 22 abuts the inner surface of pipe I2 andmaintains a fluid tight connection therebetween, this connection beingmaintained by maintaining mechanical pressure between the opposite edgesof member 22. ThisV mechanical pressure is applied by the bearingmembers 23 and 24 which serve as clamping members, member 23 beingslidably mounted on pipe 2| and member 24 being screw threaded on pipev2|, such that by turning the fastening wing fastening nut 26 in theproper direction, members 23, 24 are drawn together thereby to squeezethe annular resilient ring member 22 into abutment with the inner wallof the soil pipe.

In the process of mounting the test plug I8 on the soil pipe I2, the webmember I6 is interpositioned between the wing nut 26 and the adjacentend of clamping member 23 so that when the test plug is clamped intoposition for testing,

r from the `openend of pipe 2 I.

the shield member I4 is simultaneously clamped into position. Further,the nature of the connection between the test plug and the soil pipeallows adjustment of the position of the supported shield member I4. Theinside diameter of the smaller end of the conical member I5 issubstantially equal to the outside diameter of the soil pipe I2 so thatpreferably a close sliding it exists therebetween so 'that during Athepouring operation "concrete is precluded from entering the soil pipe I2.

After the concrete has been poured to a level vindicated in Figures 1and 3k andV then allowed to harden, the wing nut 26 is loosenedtherebyto release the pressure on the resilient member 22 to allow withdrawalof the testplug I8 with the shield member I4 assembled thereon.

The conical shape of the assembly I4 is -im-l portant in that it allowseasy withdrawal of `Vthe assembly even though the concrete is hardened'around the outsideof thesliieldli.

It'fis apparentithatthe shield member I4, if desired, may bedisassembled from-'the test plug assembly lI8 by unscrewingthe clampingmem- .ber"24"oi of the threaded` pipe 2I in which case 25 the.resilient-men'iber'-'22, clamping member 23 andshield member- I'IlY-inayin'v turn be removed After the annular'spa'ce In listhus. provided,
